PSI is a pressure.

Using Bernoulli's equation for pressure you would need a wind speed of 1660 m/s or 3713 mph to produce 200 PSI of pressure on the wind turbine blades.

The wind speeds above would be impossible.

Sir,

Thanks a lot.

what my real question is how much pressure in PSI is produced by a wind of 50 MPH on a wind mill blades.

I am working on a Project where this information is required.

thanks again

Again using Bernoulli's equation

Pressure (PA) = 1/2 "rho" Velocity^2 (rho in kg/m^3) and (Velocity in M/S)

Pressure = 1/2 (1)(22.35^2) = 250 PA

1 PA = 0.000145 PSI

250 PA = 0.0362 PSI

An "ideal" wind turbine can only utilize 59.3% of the power in the wind. Search Betz limit.
